●Streaming Assetsなら
// Application.dataPathはAssetsの直下のフォルダの事
string path = Application.streamingAssetsPath + "/myAssetBundle.unity3d";

●Assets直下なら
// Application.dataPathはAssetsの直下のフォルダの事
string path = Application.dataPath + "/myAssetBundle.unity3d";

●アセットバンドルロードに利用してみる

LoadAssetBundleData.cs

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class LoadAssetBundleData : MonoBehaviour {

    public void OnLoadAssetBundle()
    {
        StartCoroutine(LoadAssetBundle_CreateMemory());
    }

    IEnumerator LoadAssetBundle_CreateMemory()
    {
        // Application.dataPathはAssetsの直下のフォルダの事
        string path = Application.dataPath + "/StreamingAssets/myAssetBundle.unity3d";
        
        WWW www = new WWW("file://" + path);
        yield return www;
        var assetBundleCreateRequest = AssetBundle.CreateFromMemory(www.bytes);
        yield return assetBundleCreateRequest;
        AssetBundle assetBundle = assetBundleCreateRequest.assetBundle;

        Object[] objectArray = assetBundle.LoadAll();
        List<Object> myList = new List<Object>();

        myList.AddRange(objectArray);

        foreach(Object obj in myList)
        {
            Instantiate(obj);
        }
    }
}
