![]() ![]() In this study, the adhesive properties of asphalt modified with the polymers (styrene-butadiene-styrene and styrene-butadiene) and carbon nanotubes were investigated. One of the important properties affected due to oxidation is the adhesive properties of modified asphalt. However, during the service life, the oxidation affects the constituents of modified asphalt and subsequently results in deviation from the desired properties. On and after the SST full compliance date, ensuring that (i) each such worker has an SST card or a temporary SST card and (ii) each such worker who is serving as a site safety manager, site safety coordinator, concrete safety manager, construction superintendent or a competent person at such site, as required by Section 3301.13.12, has an SST supervisor card.The modification by polymers and nanomaterials can significantly improve different properties of asphalt.On and after the SST second compliance date, and until the day before the SST full compliance date, ensuring that (i) each such worker has an SST card, a limited SST card or a temporary SST card and (ii) each such worker who is serving as a site safety manager, site safety coordinator, concrete safety manager, construction superintendent or a competent person at such site, as required by Section 3301.13.12, has an SST supervisor card. ![]() On and after March 1, 2018, and until the day before the SST second compliance date, ensuring that each construction or demolition worker employed or otherwise engaged at such site by the permit holder or performing subcontracted work for or on behalf of such permit holder has successfully completed (i) and OSHA 10-hour class, (ii) an OSHA 30-hour class or (iii) a 100-hour training program.In addition to any other applicable city, state or federal law or rule, each permit holder at a building site for which a construction superintendent, site safety manager or site safety coordinator is required shall be responsible for the following: ![]()
