REDUCTION OF THE ACTUAL MODULUS OF ELASTICITY TO THE DESIGN TEMPERATURE
Journal Title: Periódico Tchê Química - Year 2018, Vol 15, Issue 0
Abstract
Reduction of the actual modulus of elasticity of road pavement to the design temperature is a rather labor intensive task. Besides, it depends on the weather and climatic conditions. Here we present the result of generalizing practical experience on this task as applied to the regions with considerable fluctuations of daily temperatures. It was found that application of fluctuations of daily temperatures when measuring deflection at the check point in the regions with sufficient solar activity makes it possible to efficiently separate the studied factor of influence on road pavement strength (temperature) at simultaneous optimization of expenses on operation of laboratory equipment. A road pavement strength indicator (invertible deflection) may vary quite considerably not only from day to day but during a day as well, especially during the design period. Under these conditions the results of linear tests of road constructions have to be reduced to the comparable ones.
