Description

. Изобретение относитс  к строительству автомобильных дорог, в частно.сти к определению относительной деформации и предела прочности при сжатии термопластичных смесей, преимуществен но асфальтобетонных. Известен способ оценки несущей способности термопластичных смесей в полевых услови х путем вдавливани  металическогоштампа нагрузкой, емой весом автомашины, и замера отно сительной деформации fl . Недостатки известного способа - ег низка  точность и невозможность определени  относительной- дефррмации дорожной конструкции в лабораторных услови х . Наиболее близким к предлагаемому  вл етс  способ испытани  бетона, включающий изготовление образца, приложение сжимающей нагрузки посредство цилшщрического штампа вплоть до разрушени  образца и регистрацию величины этой нагрузки и перемещени  штампа создава по которым суд т о физико-механических свойствах 2 JНедостатком данного способа  вл - етс  недостаточна  возпроизводимость результатов испытаний, вызванна  неопределенностью размеров образца и штампа. .. Цель изобретени  - приближение условий испытаний материала к услови м его работы в дорожных покрыти х. Поставленна  цель достигаетс  тем, что в способе испытани  бетона, включающем изготовление образца, приложение сжимающей нагрузки посредством цилиндрического штампа вплоть до разрушени  образца и регистрацию величины этой загрузки и перемещени  штампа, по которым суд т о физико-механических свойствах, образец изготавливают цилиндрическим с отношением диаметра образца к высоте и к диаметру штампа , соответственно равными 2т1 и 4-1, ... The invention relates to the construction of roads, in particular to the determination of the relative deformation and ultimate compressive strength of thermoplastic mixtures, mainly asphalt concrete. There is a method for estimating the carrying capacity of thermoplastic mixtures in field conditions by pressing in a metal pin with a load taken from the weight of a car and measuring the relative deformation fl. The disadvantages of this method are its low accuracy and the impossibility of determining the relative deflation of a road construction in laboratory conditions. The closest to the present invention is a method for testing concrete, including the manufacture of a sample, the application of a compressive load by means of a cylindrical punch until the sample is destroyed, and the registration of the magnitude of this load and displacement of the punch creates physical and mechanical properties. 2 the reproducibility of the test results, caused by the uncertainty of the sample and stamp sizes. .. The purpose of the invention is to approximate the test conditions of the material to the conditions of its work in road surfaces. The goal is achieved by the fact that in the method of testing a concrete, which includes the manufacture of a sample, the application of a compressive load by means of a cylindrical stamp until the sample is destroyed and the magnitude of this load is recorded and the stamp is displaced, which are physically mechanical, the sample is cylindrical the sample to the height and to the diameter of the stamp, respectively, equal to 2-1 and 4-1, ..
