Title:

DUST CONTROL DURING CONSTRUCTION OPERATIONS

Accession Number:

00215094

Record Type:

Component

Abstract:

SOIL AND WEATHER CONDITIONS DURING CONSTRUCTION OF HIGHWAYS ARE OFTEN CONDUCIVE TO EXTENSIVE DUST FORMATION. DUST MAY BECOME A SERIOUS HAZARD TO TRAFFIC AND TO RESIDENTIAL AREAS IF IN THE IMMEDIATE VICINITY OF THE JOB. IT ALSO PRESENTS A DEFINITE HEALTH HAZARD TO WORKING MEN. THE NECESSITY OF DUST CONTROL HAS LONG BEEN RECOGNIZED. THE MOST COMMON MEDIUM FOR DUST CONTROL HAS BEEN, AND IN MOST INSTANCES CONTINUES TO BE, THE USE OF WATER APPLIED AS OFTEN AS NECESSARY TO LAY THE DUST. TO ACHIEVE A REDUCTION IN THE COST OF FREQUENT WATER SPRINKLING, HYGROSCOPIC SALTS HAVE BEEN USED IN AREAS OF RELATIVELY HIGH HUMIDITY AND DILUTED MIXING-TYPE ASPHALTIC EMULSION HAS BEEN TRIED BY A NUMBER OF STATES. RECENTLY A NUMBER OF NEW PRODUCTS HAVE MADE THEIR APPEARANCE ON THE MARKET. ON MANY CALIFORNIA HIGHWAY CONSTRUCTION JOBS THE NEW PROJECT PARALLELS THE PRESENT TRAVELWAY OR BORDERS RESIDENTIAL AREAS WHERE THE PRESENCE OF DUST IN THE AIR BECOMES A SERIOUS PROBLEM. IN ORDER TO STUDY THE PERFORMANCE AND POSSIBLE ECONOMIC ADVANTAGES OF VARIOUS DUST PALLIATIVES, A NUMBER OF TEST SECTIONS WERE PLACED IN THE MEDIAN STRIP ON A RECENT HIGHWAY PROJECT. THE FOLLOWING PRODUCTS WERE USED: WATER, DILUTED ASPHALTIC MIXING EMULSION, A LIGNIN PRODUCT AND A RESINOUS PETROLEUM PRODUCT. WATER PROVED TO BE THE MOST EXPENSIVE AND FOR THE MOST PART THE LEAST EFFECTIVE METHOD OF COMBATING THE DUST. /AUTHOR/
