Aggregate Type(1) Application Rate (lb/yd2)

Type II 20 - 25

Type III 25 – 30

(1) See current TxDOT or ODOT material specifications micro surface aggregate gradations.

Application rates are based upon the weight of dry aggregate in the mixture. Application rates are affected by the unit weight and gradation of the aggregate and the demand of the surface to which the micro surfacing is being applied.

Provide the CO with a split certified shipping ticket for each separate emulsified asphalt shipment load prior to mixing and application.

Prior to starting application of micro surfacing, calibrate each mixing unit to be used on the project in accordance with ISSA A143 and in the presence of the CO or designated representative.

Add the following after the fifth paragraph:

Maintain quality control documentation and make available to the CO upon request and at completion of daily work. At a minimum of 4 times daily calculate the percent emulsion content, aggregate spread rate, and yield of the mixture from the equipment computer display readings and report to the CO. Maintain a daily report and log sheet containing the following information:

(a) Micro surfacing emulsion used, tons;

(b) Aggregate used, tons;

(c) Water used in the mixture, gallons;

(d) Mineral filler used, pounds;

(e) Set control agent used, gallons;

(f) Other additives used, pounds;

(g) Surface area application rate (dry pounds per square yard); and

(h) Percent of emulsion (by dry aggregate weight).

Provide copies of the daily log to the CO before the start of the next day’s production, or as directed by the CO.
