Q4 <br />Do you use a polymer modified emulsion with <br />your chipseals? <br />112 <br />17 <br />Yes, on all chipsealed <br />40 <br />roadways <br />Yes, on some chipsealed <br />27 <br />roadways <br />14 No <br />31 Unknown <br />Q5 <br />When did you start specifying the polymer <br />modified emulsion? <br />51 <br />78 <br />See Appendix K <br />Q6 <br />Have you noticed any difference in the <br />incidence of stripping/delamination on roads <br />with polymer modified emulsion? <br />65 <br />64 <br />10 Yes <br />24 No <br />31 Unknown <br />Q7 <br />Do you have any pavements which are not <br />chipsealed that are experiencing stripping <br />failures? Stripping is defined as a loss in the <br />asphalt/aggregate bond resulting in raveling, a <br />shallow surface pothole, or delamination of <br />the chipsealed surface. <br />113 <br />16 <br />Yes, this is a significant <br />4 <br />issue <br />24 Yes, this is a minor issue <br />No, we have not <br />85 experienced stripping on <br />non-chipsealed surfaces <br />Q8 <br />Is there anything else you'd like to share about <br />your use or non-use of chipseals? <br />34 <br />95 <br />See Appendix K <br />3.4 DISCUSSION AND OBSERVATIONS <br />3.4.1 Lab and field data <br />Given the extent of the field and laboratory testing, there is sufficient data to support general <br />observations that would be unsubstantiated in smaller studies.
