Types of Backfill Materials Different types of backfill materials are used in construction industry. Backfill materials that are commonly used are described below with their engineering properties. 1.
Properties of Concrete in Plastic State 1. Essential Qualities The quality of the hardened concrete is largely dependent on the quality of the plastic concrete. The curing process
Types of Concrete Pavement In pavement construction, three different concrete pavement design types are commonly used: Jointed Plain Concrete Pavements (JPCP), Jointed Reinforced Concrete Pavements (JRCP), and Continuously
Essential Properties of Asphalt Concrete Mix design methods and design requirements form an essential part for all asphalt concrete mixtures. The agency or authority responsible for paving construction
Joints in Rigid Pavement Provisions of joints are necessitated due to: 1) Expansion, contraction and warping of concrete slabs resulting from temperature and moisture changes; 2) Facilitate a
Failure of Rigid Pavement Failure in rigid pavement (or cement concrete pavement) can be identified by formation of cracks on the pavement surface. The two prime factors responsible
Failure of Flexible Pavement A typical flexible pavement consist of following 4 layers Soil subgrade Sub-base course Base course Surface or wearing course If due to any reason,
Terminologies Related to Pavement Materials ABRASION The abrasion test measures the abrasion or wear and tear resistance of the aggregate. The test is performed in the Los Angeles
DCPT or Dynamic Cone Penetration Test The dynamic cone penetrometer is a portable equipment that can be used to evaluate different layer of a pavement such as unbound
Types of Failures of Flexible Pavement Flexible pavement consist of different layers such as, Sub-grade Sub-base course Base course and Surface course If any one of the above
