EXECUTIVE SUMMARY The Port Orange Pavement Management System (POPMS) Condition Survey Manual is the first of two separate pavement maintenance management documents to be prepared by the Center for Urban Transportat ion Research (CUTR) at the University of South Aorida for the City of Port Orange. This manual is intended to provide a guideline for the survey of existing pavemen t conditions. The second document, entitled P OPMS Eva luation Report, will utilize the pavement condition survey data to determine system-wide maintenance costs and the most appropriate pavement maintenance stra tegy. 1


NTRODUCTION The Port Orange Pavement Management System (POPMS) Condition Survey Manual has been prepared by the Center for Urban Transportation Research (CUTR) at the Un i versity of South Florida to provide a g u ideline for collection of pavement distress data. The distress identification criteria herein has been adopted by the City of Port Orange so that resulting data bases will offe r opportunities for consistent eva l uation and understanding of pavement condition and performance Four asphaltic concrete pavement distress types common to the City of Port Orange, have been delineated for detailed data collection. These four d i stress types Include: (1) Alligator Cracking (2) Block Cracking (3) Edge C r acking (4) Patch Deterioration Each of these distress types are described a long w ith typical causes and location. Associated severity levels for each distress type are also described with accompanying photographic representation. Additionally, three additional distress types (rutting, raveling, and polished aggregate) have been included for general i nformation gathering purposes only These distress types, if present will be measured for extent of distress. Rnally, a POPMS Pavement Condn lon Survey form has also been included i n this manual. This form indicates that for each sample segment both a general inventory and pavement distress inventory will be recorded. All informat i on gathered on the form will be utilized as input to the maintenance priority assessment model to be documented separately, by CUTR, In the PPPMS Evaluation Report. 2


ALLIGATOR C RA C KIN G Descriptio n Allig a tor (or fatigue) c r ack ing is a series of Interconnecting cracks wh i ch are many-s ided sharp -angled pieces, us u ally less tha n on e foot on the longest sid e. causes Alligator cr ack i n g is a load associ a ted distress, cause d by fatigue f ailure of the s urface or stabilized base u nder r e peated t r affi c l oading Alligato r c r a ck i ng is I nitia ted at the b ottom of the asphalt surf ace where ten sile stress and stra i n i s highest under a wheel load. Temperatur e and moisture m a y accelerate the initiat ion and propagation o f the cracks to the surface. Initially appears as l o ngitudinal crac ks. Location Alligato r crack i ng o ccu r s only in s pecific areas tha t are subjected to repe ated t raffic loadin gs (usually in wheelpath s). Sever ity L ev e ls Low l o n g itudinal disconnected hairl ine crack(s) run n i ng paralle l to each othe r M oderate a patt e rn of p ieces f ormed by c r acks tha t ma y be li g htly spa lled. Severe cracking has progressed s o that pieces are mor e sev er e l y spelled at th e edges and loosene d un de r traffic LOw @ Madeline Ave.jHommock t 3


LONGITUDINAL AND TRANSVERSE CRACKING ( BLOCK CRACKIN G) D escrip tion Block cracklng divides the asphalt surface into rectangular pieces ranging in size from approximately 1 to 100 square feet When the distance between transverse cracks is almost the same as the width of the lane, the pavement may also crack In the longitudinal direction connecting adjacent transverse cracks Ca u ses Block cracking is caused mainly by shrinkage of the asphalt surface and t empera ture cycling. Black cracking i s not a l oad associated distress. LoCation Block cracking normally occurs o v e r a large portion of the pavement area, but sometimes it may occur on ly in non traffic areas. Severity L evels Low blocks outlined by cracks less than 1 14 inch in width with little or no spelling. Moderate blocks are outlined by cracks greater than 1 I 4 inch in width with moderate spal ling. High blacl

EDGE CRACKING Description Crescentshaped cracks or fairly continuo us crack s, parallel to, and usua lly within 1 feet of the outer edge o f the pavement. causes Edge cracking i s generally a non-load Initiated distress, created by settlement or pumping of the materi a l underlying tlhe edge of the pavement or the loss of material from non stabili zed shoul ders. Location Edge cracking occurs at the l ane / shoulder contact area or usually where paved shoulders (or curb and gutter) do not exist. Severity Level Low cracks with no breakup or raveling. Moderate cracks with some breakup or raveling. Severe Cracks with considerable breakup or raveling along the edge. t..ow@ Klngswa,yjWex ford Wo.y 5


PATCH DETERIORATION Description Deterioration in an area where the original pavement has been removed and replaced with either similar or different material Causes Traffic load, material, environment, and/or poor construction practice. Location Any asphalt patch area or utility cut. Severity Leve ls Low patch 1s 1n very good o r excellent condition and has litt le or no distress of any type. Moderate-patch is somewhat deteriorated, having low to medium levels of any types of distress Severe patch is badly deteriorated and is in need o f replacement. 6


RUTTING Longitudinal surface depression in tne wheel path. Pavement uplift may occur along the sides of the rut. Rutting is caused by inadequate compaction during construction, soft asphalt mix, or softening of the materials beneath the pavement due to moisture infiltration. RAVELING Raveling involves the wearing away of the pavement surface caused by the dislodging of aggregate particles (raveling), and loss of asphalt b ind er (weathering). Raveling is caused by hardening of the asphalt binder, low adhesion of the asphalt binder, low wear resi stance aggregate, water sensitive asphalt-aggregate mixture, or any combination of the above items. POLISHED AGGREGATE A portion of the aggregates extending above the asphalt surface are either very small, or there are no rough or angular aggregate particles to provide good skid resistance. Polished aggregate occurs along the pavement surface mainly in the wheel path, and is caused by repeated traffic application. 7
