PPT-1 Overview CQC Asphalt Specifications

In a Nutshell Payment based on Contractors Quality Control tests FDOT runs verification tests at a lesser frequency Payment is based on roadway density air voids asphalt content and gradation. This remark attributed to Henry Ford might well be used to describe the asphalt materials which are chosen to surface the majority of roads and other paved areas despite the fact that eventually under traffic and weathering the natural colour of the brPage 1br The Asphalt Advantage 11 Chapter 1 The Asphalt Advantage SMOOTHNESS STAGED CONSTRUCTION brPage 2br The Asphalt Ad anta 12 EASE OF CONSTR UCTION DURABILITY flexible ECONOMICAL In preparing these products asphalt cement is mixed with either a petroleum diluent to produce cutback asphalt or with emulsifiers water and sometimes petroleum diluent to produce emulsified asphalt Once the liquefied asphalt cement is applied durin 2 02 02 02 Flash point TOC F T 79 100 150 150 150 Distillation test T 78 Distillate percentage by volume of tota l distillate to 680F to 437F 25 10 to 500F 40 70 15 55 35 15 to 600F 75 93 60 87 45 80 15 75 Residue from distillation volume 1. 6503 Bridges. 95% in excellent to good condition..
