LOAD-TRANSFER RESTORATION OF PAVEMENTS
New pavement joints typically exhibit good load transfer, particularly if the joints are doweled. However, repeated heavy loads can cause an elongation of the dowel sockets and result in dowel looseness and a reduction of load-transfer efficiency. As load-transfer efficiency ...
SUBSEALING JOINTED CONCRETE PAVEMENTS
Purpose of Subsealing The purpose of subsealing is to stabilize the pavement slab by the pressurized injection of a cement grout through holes drilled in the slab. The cement grout will, without raising the slab, fill the voids under it, ...
DISINTEGRATION OF WBM & ASPHALT ROADS
Various Cause of Disintegration of Water Bound Macadam and Surface Treated (Asphalt Roads): 1. Inadequate stability or strength 2. Loss of binding action 3. Loss of base course materials 4. Inadequate Weaving Course 5. Use of inferior materials 6. Lack ...
Types of Distress in Bituminous Pavements and their Causes
Bituminous pavements undergo various types of distress due to various reasons. The causes of these distresses and failures of bituminous pavements are discussed. Types of Distress in Bituminous Pavements and their Causes a) Cracking in Bituminous Pavements and their Causes ...
Composition and Structure of Rigid Pavement
Composition and Structure of Rigid Pavement Rigid pavements support loads through rigidity and high modulus of elasticity of concrete slab. The loads will distribute to natural soil layer through different layers of rigid pavement. The compostion and structure of rigid ...
Los Angeles Abrasion Test on Aggregates -Values for Pavements and Roads
Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is carried out by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate ...
