SECTION 3 SUB BASE AND BASE COURSES Table of Contents AGGREGATE FOR BASE COURSES 5 STABILIZING AGENTS 6 a statement of origin and composition of all stone and/or gravel aggregates and granular materials proposed for use in the WorksThe base course or basecourse in pavements is a layer of material in an asphalt roadway race track riding arena or sporting field It is located under the surface layer consisting of the wearing course and sometimes an extra binder course If there is a sub base course the base course is constructed directly above this layer

Method Statement Roadworks 10 OBJECTIVE This Work Method Statement is to outline the apply and lay pavement for the road construction consisting of sub base of granular material road base of crusher run asphaltic concrete binder course and asphaltic concrete wearing course 20 SCOPE This methodRoad maintenance should be considered an unavoidable neces sity of living in a rural area Landowners should take the time to learn about roads because when they are well designed and maintained they have fewer impacts on the environment are more reliable and cost less to maintain than problem roads Environmental impacts

New road construction Construction of base layers A strong base for the upper road structure The bottom layer essentially comprises an unbound mixture of coarse and fine crushed stone as well as crushed sand to achieve the desired load bearing capacity and absorb traffic loads so that the underlying subgrade is not deformedSep 12 32 Tests on Aggregate Aggregate plays an important role in pavement construction Aggregates influence to a great extent the load transfer capability of pavements Hence it is essential that they should be thoroughly tested before using for construction Not only that aggregates should be strong and durable they should also possess proper shape and size to
