Description

Изобретение относитс  к дорожному строительству, а именно к оценке качества дорожных покрытий.This invention relates to road construction, in particular to the assessment of the quality of road surfaces.

Цель изобретени  - расширение информативности получаемого результата за счет выделени  сил трени  поко .The purpose of the invention is to expand the informativeness of the result obtained by allocating the forces of peace of the workout.

На фиг.1 показано устройство, общий вид; на фиг.2 - то же, вид сверху.Figure 1 shows the device, a general view; figure 2 is the same, top view.

Устройство содержит опорную раму 1 с опорами 2 и закрепленными на ней блоками 3, через которые пропущен грос, образующий с блоком 4 имитатора шины 5 неподвижную ветвь 6 полиспаста. Подвижна  ветвь 7 полиспаста св зана с составным грузом 8, а в неподвижную ветвь 6 включен гидравлический динамометр 9 с манометром 10 и самописцем 11. Имитатор шины 5 снабжен направл ющей 12, пригрузом 13 и спусковым механизмом 14.The device comprises a support frame 1 with supports 2 and blocks 3 fixed to it, through which a groove forms, which with the block 4 of the simulator of the tire 5 passes a fixed branch 6 of the polyspast. The mobile branch 7 of the polyspast is connected with the composite load 8, and the fixed branch 6 includes a hydraulic dynamometer 9 with a pressure gauge 10 and a recorder 11. The tire simulator 5 is equipped with a guide 12, a load 13 and a trigger 14.

Устройство работает следующим образом .The device works as follows.

На испытуемое дорожное покрытие устанавливают опорную раму 1 и имитатор шины 5 с направл ющей 12 и пригрузом 13A support frame 1 and a tire 5 simulator with a guide 12 and a load 13 are installed on the test road surface.

при максимальной высоте размещени  составного груза 8, фиксируемого спусковым механизмом 14. По манометру 10 самописцем 11 фиксируют нулевое показание гидравлического динамометра 9 и освобождают спусковым механизмом 14 составной груз 8 который через подвижную ветвь 7 полиспаста и блок 4 передает сдвигающее усилие на имитатор шины 5. Сцепные качества покрыти  оценивают по величине силы трени  поко  и трени  скольжени , которые определ ют величинами массы пригруза 13 и составного груза 8 с учетом показаний гидравлического динамометра 9with a maximum height of the composite load 8 fixed by the trigger 14. The gauge 10 by the recorder 11 fixes the zero reading of the hydraulic dynamometer 9 and releases the trigger load 14 of the composite load 8 which, via the movable branch 7 of the polyspast and block 4, transmits a shearing force to the tire simulator 5. Coupling The quality of the coating is estimated by the magnitude of the strength of the rest and slip friction, which are determined by the values of the mass of the weight 13 and the composite load 8, taking into account the indications of the hydraulic dynamometer 9
