Concrete Roads: PQC, Methods of Construction and

Introduction to Concrete Roads: Concrete roads fall under the category of high quality/superior type of roads built with cement concrete These pavements may or may not be provided with subbase/base courses, and they may be constructed directly over a wellcompacted soil subgrade They derive their strength to support the wheelloads of traffic from their flexural strength and are capable of1 IntroduCtIon 3 11 Scope 3 12 Definitions and Abbreviations 3 1 Concrete is used in roads, highways and airport pavements because of its load carrying capacity and low maintenance Better knowledge of speedy repair techniques would be a further advantage in supporting the use of concrete pavements This report examines the repair and restoration of concrete pavements systematically byConcrete Pavement Maintenance / RepairCEMENT and CONCRETE TECHNOLOGY Prepared by: Chapter 1: Introduction Definition of Concrete Concrete is a mixture of cement (11%), fine aggregates (26%), coarse aggregates (41%) and water (16%) and air (6%) Cement : Powder Cement + Water :Cement Paste Cement Paste + Fine Aggregate (FA) : Mortar Mortar + Coarse Aggregate (CA) : Concrete Portland cement, water, sand,CEMENT and CONCRETE TECHNOLOGY siteiugazaedups
