Therefore, an interstate <br />paving mixture will be very different from one used for a residential driveway. Differences may include types <br />and sizes of aggregate as well as the grade of liquid asphalt cement selected. <br />{.` f �L . II�'E � _ ! �: I , I . . ��� ` �_ � l F .L _ _ � E. _ f � � .

Also, liquid cements at HMA facilities are not heated to temperatures <br />as high as in roofing applications. That means that emissions and odors produced by paving operations are <br />not the same as those produced by roofing. <br />C ` \ I F ° I . , I 1 � . I C' - .' � � I � ' .

Because it is a non-toxic, impermeable material, hot <br />mix asphalt is commonly used to line fish hatchery ponds, commercial water reservoirs, and industrial retention <br />ponds. It is also used to pave recreational paths (for running & bicycling), golf cart paths, airport runways, <br />and tennis courts. Hot mix asphalt has been used in commercial livestock applications such as paving feedlots <br />and lining barn and poultry house floors for easy cleaning. Additional uses include creation of sea walls and <br />dikes to manage beach erosion. <br />�A_r� � ��r 4�F i E� E� ��� { r i> � ;.t <br />..�1 .

Some are derived directly from <br />the hot mix production components, including the burner and exhaust stack. Others are generated from move- <br />ment of the product, including trucks and loaders. Recent advancements in HMA production equipment design <br />have drastically reduced sound levels. Astec has worked to reduce sound from the hot mix process by providing <br />quieter components on a facility. Likewise, some facility owners have initiated on-site quiet operations and prac- <br />tices for movement of the product. It is often possible to participate in conversations using normal speaking <br />'' tones while adjacent to most facility components at new facilities. <br />., ,:,.: �,�1 ., .... .... ..... . .� _: � :..,..: ... ,.. .,..:. . ..., .. �... . , .� . . :.... ..�.- <br />
