SUBSTANTIATION OF PARAMETERS AND SETTING OF THE MODEL OF REPETITIVE COMPRESSIBILITY OF ROADBED BY ROAD-ROLLERS

One of the important factors influencing the serviceable life of road is the quality of its puddling, i.e. the level of its hardening. Nowadays there is no analytical dependence connecting puddling characteristic as linear load and compressibility index as puddling rate directly. The article suggests using roll unit load of road-roller as a puddling characteristic, stabilized deformation ratio with account of multiple road-roller passes as roadbed compressibility index and their analytical direct dependence.
