THE COMPACTION OF BITUMINOUS MATERIALS (PARTS 1 & 2)

The two-part article discusses the importance of compaction to ensure the performance and service life of a bituminous pavement. The mechanical properties which are dependent on the state of compaction include stiffness modulus, fatigue and creep properties. Although bituminous composition and mixing temperatures are specified in the relevant British standards, compaction is, to a large extent, left to the skill of the contractor. Although it is only in rare cases that poor road performance can be attributed to inadequate compaction, it is thought there is a case for giving more specific guidance on the compaction of different types of bituminous mixes. The article reviews compaction costs, the principles of the process and general planning for site operations. It is concluded that there will be a need to develop more economical mixes with improved properties through better compaction. Nomographs are given which relate cooling time with layer thickness, mix temperature and base temperature, and also layer compaction to specified temperatures. /TRRL/
