Use of base courses under a rigid pavement to provide structural benefit should be based on economy of construction. The first cost is usually less for an increase in thickness than for providing a thick base course. However, thick base courses have often resulted in lower maintenance costs since the thick base course provides stronger
Rigid Pavement Maintenance is more than just a collective set of specific pavement maintenance techniques. It is a way of thinking and the guiding force behind an agency's financial planning and proper asset management. Pavement management must be tailored to each road agency's system to meet the need of various pavement distresses in the most ...
Revised April 2007 Chapter 7 Pavement Maintenance Rigid Pavements Rigid pavements are normally composed of portland cement concrete (PCC) as the prime structural element. Depending upon conditions, the pavement slab may be designed with plain, lightly reinforced, continuously reinforced, pre-stressed, or fibrous concrete.
Types of Pavement Maintenance Pavement maintenanceis the key to pavement preservation. An effective pavement preservation program integrates many maintenance strategies and treatments. There are three types of pavement maintenance: Preventive Maintenance:Planned strategy of cost-effective treatments to an existing roadway system and its

collection of data for various rigid pavement designs based on rigid pavement construction site situated in Nagpur, Maharashtra, India. Key Words: Rigid Pavement, Rigid Pavement Layers, Materials of Construction, Pavement Maintenance, Pavement Drainage 1.INTRODUCTION A pavement is an important structure consisting numerous
The rigid pavement has rigidity and high modulus of elasticity to distribute the load over a relatively wide area of soil. Fig: Rigid Pavement Cross-Section. Minor variations in subgrade strength have little influence on the structural capacity of a rigid pavement. In the design of a rigid pavement, the flexural strength of concrete is the ...
Rigid pavement distress is a serious issue all over the world, the distresses causes some serious problems at wide range. Prevention of rigid pavement distresses is a challenge to the Engineers. Maintenance and Rehabilitation is to be properly done to prevent the distresses in rigid pavement. The common distresses occurred on pavement is as ...
Rigid pavement, if designed and built properly, provides excellent long-term performance with little maintenance required. However, for various reasons, distresses occur and repair/rehabilitation becomes necessary. Compared with repair/rehabilitation of flexible pavement, rigid pavement repair/rehabilitation costs more and, if not done properly ...
Maintenance of Flexible & Rigid Pavement Objective of Road Maintenance • The routine work performed to keep a pavement, under normal conditions of traffic and normal forces of nature, as nearly as possible in its as constructed condition. • The function of preserving, repairing, restoring a pavement and keeping it in condition for safe, convenient, and economical use.
Preventive Maintenance and Pavement Preservation A preventive maintenance program is a systematic approach to using a series of preventive maintenance treatments over time. One treatment will improve the quality of the pavement surface and extend the pavement life, but the true benefits of pavement maintenance are realized when there is a
Rigid Pavement Roads. Tensar geogrids can help you build stronger, longer-lasting rigid pavements. Building a rigid pavement structure with a geogrid layer will reduce deformation better than extremely thick aggregate base sections. This enhanced pavement design creates a more uniform and resilient pavement structure.
pavement design alternative will perform over its intended lifetime. This evaluation is performed by predicting the distresses that will occur in the pavement at the end of each year in the lifetime of the pavement. If the distresses are severe enough to require attention, rehabilitation and maintenance activities will be specified and the
ment types considered were flexible pavement, rigid pavement, and resurfaced pavement. For each of the 820 sections, four major groups of information were summarized: traffic, pavement characteristics, climatic zone, and pavement mainte nance records. Traffic infonnation included average
Rigid pavements can serve up to its design service life and even beyond if timely repairs are undertaken. All types of pavements deteriorate with time. Rate of deterioration is comparatively much slower than flexible pavements. The following figure indicates the typical treatment which may be considered with the age of Pavement.
CRACKING IN RIGID PAVEMENTS Rigid pavement consists of concrete slab. The concrete slab cannot be of indefinite length because concrete slabs of large lengths develop stresses in itself due to shrinkage and expansion and causes concrete slab to crack. These stresses may be due to temperature changes warping or friction. Cracks in a long slab may be random cracks and of irregular shape.
Maintenance actions, such as crack sealing, joint sealing, fog seals and patching help slow the rate of deterioration by identifying and addressing specific pavement deficiencies that contribute to overall deterioration. Rehabilitation is the act of repairing portions of an existing pavement to reset the deterioration process.
This design period is dependent on the nature and level of maintenance schedule. The design life may be taken as 10 to 20 years for low-traffic volumes (flexible pavements) and 20 to 30 years for high-traffic volumes, (rigid pavement) depending on the designer's discretion [IRC37-2001 and IRC58-2002]. 2.
The flexible pavements are less expensive also with regard to initial investment and maintenance. Although Rigid pavement is expensive but have less maintenance and having good design period. The economic part are carried out for the design pavement of a section by using the result obtain by design method and their corresponding component layer ...

The maintenance treatments applied were slurry seal, chip seal, crack seal and thin overlay. SPS-4: Preventive Maintenance Effectiveness of Rigid Pavements. SPS-4 compares the effectiveness and mechanisms by which the selected maintenance treatments preserve and extend pavement service life, safety, and ride quality.
Concrete pavement acts as a beam when carrying a moving load. The load carrying capacity of a concrete pavement is a function of the strength of the concrete, the strength of the subgrade and the thickness of the concrete slab.
