Cohesion of Slurry Surfacing mix is an important technological indicator that allows you to start traffic on time. In this article Slurry Surfacing mix curing is studied in three modes: 10 °C (high humidity), 20 °C (normal humidity) and 30 °C (high humidity). As binders for Slurry Surfacing mix there were used oxidized bitumens produced from light crude-oil and distillation bitumen produced from heavy crude-oil. There was confirmed that the first bitumens are characterized by low acid numbers, while the latter ones – by high ones. On the base of the bitumens there were produced cationic slow-setting bitumen emulsion and Slurry Surfacing mix. It was found that high-acid number bitumen is definitely optimum version in comparison with low acid number for the usage in Slurry Surfacing mix at different temperature modes – by criterion of cohesion strength build-up rate for the mix. This criterion consists of three periods (times) on mix curing: Set («Set» Torque), Traffic (Early Rolling Traffic) and Cure Time (Cured Slip Torque).
