Prediction of cooling curves for hot-mix paving materials by a computer program
The structural performance of a bituminous or macadam pavement depends upon the effectiveness of the compaction of the hot paving materials during the pavement's construction. To be effective the compaction process should be completed before loss of heat causes the paving material to become stiff and unworkable. It is therefore important to know the rate of cooling of the hot material after lay…
A computer program to analyse the economics of the trafficking of a sub-base …
Trrl Lr 781 A computer program designed to analyse the economics of the operation of construction traffic on a sub-base pavement is described. The program examines the overall costs associated with different strategies for paving, transport and sub-base construction with a view to selecting the strategy which minimises the overall cost. Options available in the program permit the investigation…
Measurement and assessment of unevenness on major roads
The report describes the derivation of evenness criteria for use on new and in-service roads. Seperate criteria for the evaluation of ride over road subsidence and overlay ramps are also presented. The eveness criteria were developed by comparing the unevenness of new and in-service roads with the subjective assessments of road users. The application of the criteria using profile measurements m…
