Summary
The instrument is designed and made as per T 0755-2011 "Load Wheel Burnt-on Sand Test for Slurry Mixtures" in the Traffic Standard of the People's Republic of China JTG E20-2011 "Highway Engineering Bitumen and Bituminous Mixtures Test Code" .It is suitable to control the upper limit of asphalt used in the slurry mixtures .It can confirm the best asphalt content of slurry mixtures together with wet wheel abrasion test .
I.Main technical Characteristics
1.The instrument adopts floor type structure .The structure design,the specifications size of test apparatus ,act,each can meet the requirement of T 0755 standard .Novel design ,reasonable structure and convenient to use .
2.The part design of the mechanical transmission has safety protection device to prevent from injuring the operator accidently .It is stable and safe .
3.Frequency of rolling compaction can be preset by the operator during the test .When the instrument working ,it can automatic count ,until the count value is equal to the set value ,the counting stop and the instrument stop working .
