    11 year evaluation of fabric form with cement fly ash mixture for erosion and sediment control (OK-98-02) 2110
    (1998-6) Brockelsby, Sr., Rudy L.; Oklahoma Department of Transportation. Materials and Research Division. Office of Research & Implementation
    Addendum to 1987 Final Report. Short brief of the construction and reference to previous recommendations, major objectives, and notation of conclusions. Findings, observations, and pictures showing long term effects to fabric fonn. Conclusions and recommendations for long term effects. This addendum constitutes a follow-up to Item 2114; 81-08-1, "FabricForms". Major Conclusions: Fabric Form can be utilized with little preparatory work. Nylon resists ultraviolet radiation and bonds with the mortar mix better than the polypropylene. The pillowed effect of the fabric collects sediment, thereby encouraging vegetative growth. Weep hole should be used. Lesser slopes result in greater abrasion to the material.

    Fabric form with cement fly ash mixture for erosion and sediment control (FHWA-OK-87-8) 2114

    A study was c on duc t ed in Ok l ahoma in 1 98 3 t o det ermine the p erformanc e o f f abr i c form mats fi l led with different prop o r t i ons o f f ly ash c ement grout mixtures . They were used to r epair a 2 8 5 ft l ong severely ero ded d i t ch . The mat was f i l l ed with three d if f erent mixtures . They were crnmp osed o f 1 0 0 p er c ent c ement , a 5 0 - 5 0 mixture o f f l y ash and c ement and an 8 0 p er c ent fly ash 2 0 p er c ent c ement mix ture . The p r o ject was eva lua t ed by the Ok l ahoma Dep ar t ment o f Transpor t a t ion Research Division for a p er iod o f four years fo l l owing the inst a l l at ion o f the fabr i c form mat . A cost ana l ysi s was made comparing the fabr i c form ma t eri a l t o convent i onal concret e d i t ch l iner . I t was c onc luded that fabr i c form p erforms wel l and is cost effec t ive , and that C l ass c f ly ash be a l lowed in grout mixtures . I t is recommended that , the fabr i c form inst a l l at ion be mon i t ored with core samp l es t aken p er i o di c a l ly for t he next 1 0 years . A p rop osed sp ec i f i c a t i on is inc luded in the app endix o f this r eport . Also , a video t ap e showing the inst a l lat ion o f the f abr i c form mat is ava i l able upon r equest .
