If The Length Of The Last Unit Is Shorter Than ½ Of The Normal Lot Length, It Shall Be Included In The Previous Lot. Other Areas Such As Intersections, Entrances, Crossovers, Ramp, Etc., Will Be Grouped Together To Form A Lot. Small Irregular Areas May Be Included With Other Unit Areas To Form A Lot. Each Lot Will Be Divided Into Five (5) Equal Segments And One Core Will Be Obtained From Each Segment In Accordance With Aashto T 24. 2. Pavement Thickness It Is The Intent Of This Specification That The Pavement Has A Uniform Thickness As Called For On The Plans For The Average Of Each Lot As Defined. After The Pavement Has Met All Surface Smoothness Requirements, Cores For Thickness Measurements Will Be Taken. In Calculating The Average Thickness Of The Pavement, Individual Measurements Which Are In Excess Of The Specified Thickness By More Than 5 Mm Will Be Considered As The Specified Thickness Plus 5 Mm And Measurement Which Are Less Than The Specified Thickness By More Than 25 Mm Shall Not Be Included In The Average. When The Average Thickness For The Lot Is Deficient, The Contract Unit Price Will Be Adjusted For Thickness In Accordance With Paragraph (3 Below). Individual Areas Within A Segment Found Deficient In Thickness By More Than 25 Mm Shall Be Evaluated By The Lgu Project Engineer, And If In His Judgment, The Deficient Areas Warrant Removal, They Shall Be Removed And Replaced By The Contractor With Pavement Of The Specified Thickness At His Entire Expense. However, If The Evaluation Of The Lgu Project Engineer Is That The Deficient Area Should Not Be Removed And Replaced, Such Area Will Not Be Paid. When The Measurement Of Any Core Is Less Than The Specified Thickness By More Than 25 Mm, The Actual Thickness Of The Pavement In This Area Will Be Determined By Taking Additional Cores At No Less Than 5 M Intervals Parallel To The Center Line In Each Direction From The Affected Location Until A Core Is Found In Each Direction, Which Is Not Deficient In Thickness By More Than 25 Mm. The Area Of Slab For Which No Payment Will Be Made Shall Be The Product Of The Paving Width Multiplied By The Distance Along The Center Line Of The Road Between Transverse Sections Found Not Deficient In Thickness By More Than 25 Mm. The Thickness Of The Remainder Of The Segment To Be Used To Get The Average Thickness Of Each Lot Shall Be Determined By Taking The Average Thickness Of Additional Cores Which Are Not Deficient By More Than 25 Mm. 3. Adjustment For Thickness When The Average Thickness Of The Pavement Per Lot Is Deficient, Payment For The Lot Shall Be Adjusted As Follows: Deficiency In The Average Thickness Per Lot (mm) Percent (%) Of Contract Price Per Lot 0 – 5 100% Payment 6 – 10 95% Payment 11 – 15 85% Payment 16 – 20 70% Payment 21 – 25 50% Payment More Than 25 Remove And Replace/ No Payment No Acceptance And Final Payment Shall Be Made On Completed Pavement Unless Core Test For Thickness Determination Is Conducted 311.4 Environmental Measures In Loading Cement To The Truck And Unloading It To The Temporary Bodega, And From The Bodega To Batching Plant And During Concrete Work Operation Workers Doing This Job Shall Be Provided With Gears So As To Avoid Inhaling Cement Dust Particles That Could Affect Their Health.
