A common mistake that is made in selecting a geosynthetic material, is looking at the unit cost for one component rather than the cost of all units involved. Let's say the installed cost of backfill material is $30 per ton, but you reduce the thickness by 1 inch. This provides a savings of a dollar per square yard. Now introduce a geosynthetic material that costs $4 per square yard, but it reduces the thickness of the gravel by 8 or 9 inches, your cost for the solution has now been reduced by [...] now been reduced by $5 per square yard. To estimate costs when using geosynthetic materials, there is design software and calculation tools available to engineers, contractors, etc. [...] ## Geosynthetics vs Traditional Material: How Are They Cost Effective?
Geosynthetics can have an overall lower product cost than that of traditional substances in most applications. Through life cycle cost analysis, geosynthetics have been a well accepted product used in natural disaster reconstruction, site development and the creation of roads for over 30 years. There are several advantages to using geosynthetics and they are:

most applications, geosynthetics usually offer lower production costs than traditional solutions. Geosynthetics can be shown to be the best products used in landslide rehabilitation and natural disaster reconstruction through life cycle cost analysis. In fact, there are several advantages when using geosynthetics: space savings; avoidance of costly ‘remove and replace’ methods; possible use of locally available lower quality backfill materials; low maintenance due to long life cycle; lower time [...] for landslide stability purposes. Whether in landslide or other applications, when compared with conventional approaches, geosynthetics-based solutions have demonstrated reduced material use and lower costs for materials, construction and maintenance works. [...] In general terms, economically, at the construction level of slope stabilization, different studies have proven that a construction solution that opts for geocomposites is much more economical and efficient. The use of geosynthetics may reduce or even eliminate waste deposits. Furthermore, geosynthetics can also serve as reinforcing and/or drainage materials to accelerate the consolidation of soft subgrades, thereby reducing execution times, transportation, and general construction-related

almost a year for completion of the settlement without the geosynthetic. Performance: Piezometers at the base and middle of the slope during construction confirmed the test pad results. Deformations of the geotextile in the side slope were also monitored and found to be less than the precision of the gages (± 1% strain). Cost Effectiveness: The cost of the geotextile was approximately $1/yd2 . In-place costs of the geotextile, along with the on-site fill averaged just over $3/yd3 for a total [...] minor problems have been reported with respect to the erosion control measured and some minor differential movement in one of the lower sections of the embankment. Cost Effectiveness: The project was constructed in 1989 at a cost of approximately $17/ft2 of vertical face. 166 Case Study #56: Lost Trail Roadway Widening Location: Salmon, Idaho Engineer: Federal Highway Administration Purpose: Support Structure for Roadway Geosynthetic Material: Reinforcement: Geotextile (1370 lb/ft & 6850 [...] improving traffic safety. Cost Effectiveness: The value of this reinforced slope has proven to be very good, with its cost being around 50% of the cost of the originally proposed bridge solution. 150 Case Study #39: Langkawi Landslide Restoration Location: Kedah, Malaysia Owner: Kuala Lumpur Public Works Department Engineer: KGA Consultants Contractor: Protab Construction Purpose: Support Structure for Roadway Geosynthetic Material: Reinforcement: Geocomposite Drainage: Polypropylene

and pre-loading. The Geosynthetic Solution Geosynthetics are proving to be a cost effective alternative to traditional road construction methods. As a result, the application of geosynthetics to the construction of unpaved roads over soft subsoils has become quite popular. Design has focused on the stabilization of the subgrade and the reinforcement of the aggregate, leading to the identification of two important functions: membrane action and lateral restraint. Membrane action is the ability [...] is improved by the addition of cement, lime, or excess aggregate. In any case, the traditional solution is often costly and always time consuming. The Geosynthetic Solution As was noted earlier, geosynthetics are proving to be a cost effective alternative to traditional road construction methods. In paved roads, lateral restraint also called confinement is considered to be the primary function of the geosynthetic. With the addition of an appropriate geosynthetic, the Soil-Geosynthetic-Aggregate [...] cement, lime) or injections • Reinforcement of the soil matrix using a structural element. Geosynthetic Solutions Geosynthetic solutions include geotextiles, geogrids and combinations of geotextiles and geogrids. While a wide variety of site improvement methods have been used during the past decade, soil reinforcement has emerged as an efficient, economical and effective solution to the problem of constructing embankments over soft soils.
