Shuliak I. Road constructions test methods improvement in the process of road diagnosis

The thesis is devoted to the road pavements testing methods improvement for road diagnostics by their productivity, accuracy, informativity and safety increasing. The method of static stamp tests, with developed automated measuring station use is proposed, which allows repeated loads performing with their significant duration decrease. For the first time ever a new method of actual elasticity modulus determining by impact duration on the basis of road structure dynamic load mathematical model improvement is substantiated. Method of road pavements stability evaluation to the ridge formation by means of a spherical stamp with repeated dynamic loads, the efficiency of which was confirmed by a numerous research in the field conditions is developed.
